4.4.2 WIRING DIAGRAM

The diagram below shows the main components of the electrical circuit:
1. General power supply
2. Red start switch
3. Motor
4. Circuit breaker
See Figure 3
4.4.3 FOUR-WAY CLAMP
The clamp is designed to hold a different family of keys on each of its four sides:
SIDE 1: Keys held by the SHAFT and NORMAL blade
SIDE 2: Keys held by the SHAFT and NARROW blade
SIDE 3: Keys held by the LOWER RIDGE
SIDE 4: Keys held by the UPPER RIDGE
See Figure 4

5- OPERATION AND FUNCTIONS

5.1 DEPTH ADJUSTMENT

• Disconnect the rear plug from the power supply to perform this operation in complete safety
and make it impossible for the cutter to start moving.
• Secure the two adjustment keys (R) in "side 1" of the clamps so that the lower edge of the
adjustment key is in contact with the inner face of the clamp (J).
• Raise the carriage to move the clamps closer to the cutter (C) and the tracer (T).
• Position the tip of the tracer (T) against the flat edge of the adjustment key. While in this posi-
tion, manually rotate the cutter one full rotation in the opposite direction to standard operation.
- The depth has been set correctly when the cutter brushes slightly against the adjustment key.
- If the cutter rotates freely, it is too far back from the tracer and the cutting gear is set too shallow.
The depth requires adjustment.
- If the cutter gets stuck on the adjustment key, it is too far forward from the tracer and the cutting
gear is set too deep. The depth requires adjustment.
• To adjust the cutter depth, move the micrometric tracer as follows:
- Loosen the stud bolt (S) to release the tracer but leaving the stud bolt (S) very gently touching
the hidden part of the tracer. This will avoid any involuntary rotation of the tracer when moving
it forwards or backwards.
- Rotate the control wheel (W) clockwise to move the tracer backwards.
- Rotate the control wheel (W) anti-clockwise to move the tracer forwards.
• Once the depth has been adjusted, re-secure the tracer using the stud bolt (S).
See Figure 6

5.2 LATERAL ADJUSTMENT

• Lateral adjustment is fixed and calibrated during factory assembly. It will therefore not need to
be adjusted. You can check that this calibration has been performed correctly as follows:
• Disconnect the rear plug from the power supply to perform this operation in complete safety
and make it impossible for the cutter to start moving.
• Secure the two adjustment keys (R) in "side 1" of the clamps so that the lower edge of the
adjustment key is in contact with the inner face of the clamp (J).
• Ensure that the faces of the stopper support (H) coincide perfectly with the upper edges of the
adjustment keys (R). If this is not the case, loosen the stopper screw (H) on the right-hand side and
re-secure it in its correct position.
Raise the carriage to move the clamps closer to the cutter (C) and the tracer (T).
• Insert the tip of the tracer (T) into the notch on the adjustment key (R). While in this position,
manually rotate the cutter one full rotation in the opposite direction to standard operation. Ensure
that the cutter brushes slightly against the notch of the adjustment key.
See Figure 7

5.3 KEY COPYING

• Rotate the clamps to the side you will use for holding the keys.
• Insert the original key into the left-hand clamp so that the notched section more or less coin-
cides with the edge of the clamp. With the key in this position, secure it in place by rotating the
knob (A).
- When using SIDE 1 or 2: support the shaft of the key correctly on the base of the clamp.
- When using SIDE 3 or 4: correctly insert the key guide into the clamp guide.
• Insert the blank key into the right-hand clamp and align the two keys as follows:
- Raise the stoppers using their corresponding knob and support them against the upper shoulders
of the keys.

- With the blank key in this position, secure it in place using the knob (A).
NOTE: Both the original key and the blank key should be inserted from the left-hand side of their
clamps.
- Remove the stoppers from the keys so they do not interfere with the key cutting process.
• Switch on the machine so the cutter begins to rotate.
• Bring the keys towards the cutter (C) and the tracer (T). Remember that you should work from
left to right.
• Press the original key against the tracer and begin the duplication process, moving the carriage
assembly sideways.
• After completing the duplication process:
- Return the carriage assembly to its rest position.
- Switch off the machine so the cutter stops rotating.
- Release the keys from the clamps.
- If the duplication process produced any burrs on the copy, these can be removed using the brush
that is provided with the machine for this purpose.
See Figure 8

5.3.1 COPYING A KEY WITH NO SHOULDER

• Insert the chocks (Y) into one of the vertical slots on one of the four sides of the clamps.
• Insert the original key into its clamp until the key tip rests against the chock (Y). With the key
in this position, secure it in place by rotating the knob (A). Repeat this process with the blank key.
• Remove the chocks (Y), raise the carriage assembly and begin the duplication process.
See Figure 9

5.3.2 COPYING A CRUCIFORM KEY

• Use SIDE 1 of the clamp for this type of key.
• Insert the star key chocks (X) into the vertical slots in the clamps so that the gap in the chock is
facing the cutter or tracer.
• Insert the original key into its clamp until the key tip rests against the chock (X). With the key
in this position, secure it in place by rotating the knob (A). Repeat this process with the blank key.
• Raise the carriage assembly and begin the duplication process.
• These keys have three notched blades. So the same steps will need to be repeated twice more
for the remaining two key blades.
See Figure 10

6.- MAINTENANCE

The Berna simply duplicator machine requires no particular maintenance plan. Nonethe-
less, certain parts should be checked regularly and eventually replaced once they become
worn. This particularly includes the cutter, the brush, the tracer and the belt.
Maintenance operations should be carried out by qualified professionals with the neces-
sary protective equipment for working safely. The instructions provided in this manual
should be followed carefully when performing any maintenance tasks and the following
instructions should be followed in general:
Before starting any maintenance operation, the machine must be turned off and
disconnected from the electrical network. The operator must ensure that no one
can access the machine.
Do not carry out any maintenance operation while the machine is running.
Original spare parts must always be used. The "CE" mark is guaranteed only if
original spare parts supplied by the manufacturer are used.
After the replacement of a component, make sure that the corresponding screws
are properly fastened.
DO NOT USE COMPRESSED AIR AT ALL! To keep the jaws and the carriage clean
of metal chips, it is recommended to use the brush supplied with the machine.
To protect the metal parts of the machine against oxidation, it is recommended
to use protective oil of the type WD40 or similar, applying it on clamps, tracers,
guides, etc...

6.1 BRUSH REPLACEMENT

The brush should be replaced when it can no longer remove burrs.
por otro.
Do so as follows:
Switch off the machine and unplug the power cord.
1) Use the Nº 4 Allen key to release the two screws holding the transparent cutter protection
shield in place.
